Imam Ali (as): The believer is such that his joy is evident on his face whereas his sorrow is in his heart. His breast is at its widest [i.e. biggest heart] but his ego is at its lowest. He despises high rank and shuns reputation. His grief is long-lasting and his ambition is lofty. His silence is much and his time occupied. He is grateful, extremely patient, and immersed in deep thought. He is thrifty with his needs. He is good-natured and mild-tempered. His soul is firmer than steel whilst he [i.e. his ego] remains lower than a slave. Nahj al-Balāgha
